The Non-contact ultrasound (NCU) technology was used as an alternative to characterize the physical properties of asphalt binder. The objective of this research is to correlate the physical properties of asphalt binder with non-contact ultrasound measurements. The physical properties of asphalt binder are viscosity and penetration. In this study two types of' AC 30 and AC40 asphalt binders are used. For each type of asphalt binder there are original and aged samples. The non-contact ultrasound measurements are integrated response (IR) and wave velocity (Vm). The IR is the attenuation value of the area underneath the signal wave measured in decibels and can be used to measure the amount of ultrasonic energy transmitted or reflected from a test material. The wave velocity is the velocity of the ultrasound when it passes through the material. The results show that IR can he correlated with physical properties: however wave velocity does not correlate well.
